The Science

Reading people isn't intuition, magic, or a trick. It's a discipline with sixty years of peer-reviewed research — and a graveyard of popular claims that don't hold up. This page is the audit trail of what we teach and what we reject.

The five pillars of our curriculum

Every lesson in Cipher Academy traces back to one of five disciplines. Each was chosen because (a) it has produced replicated effects in peer-reviewed journals, (b) it has practical field validation outside the laboratory, and (c) it survives the scrutiny of skeptics inside the same field. We cite primary sources, not popularizations.

1. Persuasion — Robert Cialdini

Cialdini's seven principles of influence — reciprocity, commitment & consistency, social proof, authority, liking, scarcity, and unity — have been replicated across dozens of independent studies over four decades. Influence: Science and Practice remains required reading at FBI Academy hostage-negotiation courses. We teach all seven with their boundary conditions, including the failure modes Cialdini himself documents.Cialdini, R. (2009). Influence: Science and Practice (5th ed.). Pearson. ISBN 978-0205609994.

2. Tactical negotiation — Chris Voss

Voss spent 24 years as the FBI's lead international kidnapping negotiator. The framework in Never Split the Difference — tactical empathy, mirroring, labeling, calibrated questions, the accusations audit, Black Swans — has been field-tested in over 150 hostage negotiations with documented outcomes. We teach the methods as Voss teaches them at Georgetown, not as Twitter threads remix them.Voss, C. & Raz, T. (2016). Never Split the Difference. Harper Business. ISBN 978-0062407801.

3. Body language & status — Joe Navarro, Keith Johnstone

Navarro's 25 years of FBI counterintelligence work gave us the “3 C's” — context, clusters, and consistency — the only framework for nonverbal interpretation that has survived replication outside the laboratory. We pair it with Keith Johnstone's status dynamics from Impro, which formalized the rule that humans constantly negotiate dominance through micro-cues. We do not teach single-tell shortcuts (see the rejection list below).Navarro, J. & Karlins, M. (2008). What Every BODY Is Saying. William Morrow. ISBN 978-0061438295.Johnstone, K. (1979). Impro: Improvisation and the Theatre. Faber & Faber. ISBN 978-0571111107.

4. Cognitive biases — Daniel Kahneman

Kahneman won the 2002 Nobel Prize in Economics for work that founded behavioral economics. The biases we teach — anchoring, loss aversion, framing, halo, availability, planning fallacy — have been replicated in thousands of independent studies and form the empirical core of modern decision science. We use the surviving experiments (Kahneman & Tversky's original prospect theory) and explicitly flag the ones that failed replication.Kahneman, D. (2011). Thinking, Fast and Slow. Farrar, Straus and Giroux. ISBN 978-0374533557.

5. Truth-seeking — Aldert Vrij, SUE technique

Detecting deception from behavior alone tops out at around 54% accuracy — barely above chance. What works is the cognitive approach: increasing cognitive load on the interviewee, then comparing their statements against strategically-released evidence (Strategic Use of Evidence, or SUE). Vrij's methods have raised lie-detection accuracy to 67% in controlled trials.Vrij, A. (2008). Detecting Lies and Deceit: Pitfalls and Opportunities (2nd ed.). Wiley. ISBN 978-0470516256.Granhag, P. A. & Hartwig, M. (2008). A new theoretical perspective on deception detection: On the psychology of instrumental mind-reading. Psychology, Crime & Law, 14(3), 189–200.

What we publicly reject

Our curriculum is defined as much by what it excludes as what it includes. The following claims have not survived replication, were never empirically supported in the first place, or are commonly misquoted. We name them so you don't encounter them inside Cipher.

Crossed arms mean defensiveness

There is no single nonverbal cue that reliably maps to a specific emotional state across contexts. Navarro himself rejects this in What Every BODY Is Saying: people cross their arms when they are cold, comfortable, thoughtful, or just self-soothing. Context, clusters, consistency — never a single gesture.

Nose-touching means lying

DePaulo and colleagues' 2003 meta-analysis of 158 deception cues found that the effect size for nose-touching as a deception indicator is essentially zero.DePaulo, B. M., Lindsay, J. J., Malone, B. E., Muhlenbruck, L., Charlton, K., & Cooper, H. (2003). Cues to deception. Psychological Bulletin, 129(1), 74–118.

NLP eye-accessing cues reveal truth or fabrication

The claim that eye direction (up-left vs. up-right) maps to whether someone is recalling or constructing was tested by Wiseman, Watt & colleagues in 2012 with three studies; no relationship was found.Wiseman, R., Watt, C., ten Brinke, L., Porter, S., Couper, S. L., & Rankin, C. (2012). The eyes don't have it: Lie detection and neuro-linguistic programming. PLOS ONE, 7(7), e40259.

Mehrabian: 7%-38%-55% rule

Albert Mehrabian never claimed this. His 1967 studies measured how people interpret messages where the verbal and nonverbal content are contradictory, in a constrained laboratory setting. Mehrabian has repeatedly stated that the numbers were misappropriated and do not apply to general communication. We do not cite the rule.

Microexpressions enable lie detection

Jordan et al. (2019) found that recognising microexpressions correlated poorly with lie-detection accuracy. The cognitive approach (Vrij, SUE) outperforms microexpression-based methods.Jordan, S., Brimbal, L., Wallace, D. B., Kassin, S. M., Hartwig, M., & Street, C. N. H. (2019). A test of the micro-expressions training tool. Journal of Investigative Psychology and Offender Profiling, 16(3), 222–235.

Power posing alters hormones

Carney, Cuddy & Yap (2010) reported a hormonal effect from two-minute “power poses,” but the original first author (Carney) later disavowed the result in 2016, and large pre-registered replication attempts have failed to reproduce the testosterone / cortisol findings. We teach status mechanics from Johnstone's replicated framework instead.Ranehill, E., Dreber, A., Johannesson, M., Leiberg, S., Sul, S., & Weber, R. A. (2015). Assessing the robustness of power posing. Psychological Science, 26(5), 653–656.

Why this matters

The reading-people genre is dominated by pseudoscience because it sells. We build Cipher to be the opposite: every lesson cites a primary source, every framework states its boundary conditions, and every popular myth gets a public obituary. If we ever teach something that fails replication, we remove it and tell you why.

If you find a citation in Cipher you believe is misapplied, write to info@cipheracademy.net. We publish corrections within 30 days.
